All you need is to run a small script which using mdb will set it up.
I have come up with the following dtrace script. I'm not sure that it
is gathering exactly the values that I (or you) would want, I
developed mainly as a test to see how much I really wanted to push an
RFE to get ARC stats into kstat.
#! /usr/sbin/dtrace -Cs
#pragma D option quiet
BEGIN
{
printf(" MIN MAX CUR TARGET\n");
printf("------ ------ ------ ------\n");
}
profile:::tick-10s
{
printf("%6d %6d %6d %6d\n",
(long long) zfs`arc.c_min / 1024/1024,
(long long) zfs`arc.c_max / 1024/1024,
(long long) zfs`arc.size / 1024/1024,
(long long) zfs`arc.c / 1024/1024);
}
